Cabin Air Filters

June 2012

Cabin air filters are common in later model automotive and heavy-duty on- and off-highway applications.

These filters reduce the amount of airborne pollutants and particles entering the interior of a vehicle through its heating, ventilation and air conditioning system (HVAC), by capturing dust, pollen and other airborne contaminants.

A cabin air filter will protect passengers from airborne pollen, bacteria, dust and smog, reduce dust and dirt accumulation in the vehicle's interior and increase air conditioning and heat output and performance.

Most cabin air filters are in a location that makes it moderately easy to access and replace. Cabin air filters are typically located under the hood or cowl, or behind or under the glove compartment. The cabin air filter should be changed every year or 12,000-15,000 miles (19,000-24,000 kilometers).

Hastings automotive cabin air filters come with easy-to-use installation instructions, which are also available online. These step-by-step instructions tell you where to locate your cabin air filter and how to replace it.
